Jennifer Lopez: I'd Marry Again!

She's off American Idol. But not off the marriage bandwagon.

Despite having struck out three times with husbands, Jennifer Lopez tells ABC News that she'd absolutely walk down the aisle again if the opportunity presented itself.

"For me, the biggest dream is the fairy tale," Lopez told ABC News's Amy Robach."I will never give up on that dream."

The most likely candidate to be husband number-four, of course, is J. Lo's current boyfriend, Casper Smart. The 25-year old told the same network that he's totally smitten with Lopez, but it wasn't love at first sight.

"I don't think it was for either of us," he says. "It was very natural how it happened. There was nothing before. No flirting, nothing before. Just natural. It just happened."

And what's it like to work with one's significant other?

"Sometimes I tell her something – you know, give her notes," says Smart, who is the main choreographer on Lopez's tour. "Sometimes she gives me notes. But at the end of the day, it doesn't matter whose position is what because she's the boss."

Insert your obvious sexual joke here, readers.
